Hi
@Neeny84 . Whatever you do will take time to have effect, so don't assume there will be an improvement today or tomorrow. The other thing is that if you're stressed, it will tend to result in your liver raising your blood glucose, so it's also worth trying to relax.
Your liver will usually be trying its best to maintain your BG levels at what it's come to accept as a "normal" level for you. But livers are slow learners, and it takes time for them to adjust to change. This is probably the case for everyone.
At the moment for you that "not normal normal" looks to be around high sevens/eights. Don't fret too much about the decimal points - there's sufficient inaccuracy in the test to explain that - for example, a true BG value of 6.0 could produce test results anywhere from 5.1 and 6.9, and still be "acceptably accurate".
If you are not seeing substantial differences between your pre-meal and +2hr readings, I would tend to think that you are limiting carbs in those meals to the point where your system can cope fairly well. In other words, your issue as presented is not so much what's in your food at the minute, but more the fact that your system is still geared to "normal" being around 8mmol/l. That doesn't mean that other meals/drinks/snacks aren't contributing to it.
That will take time to change. In the short term, some people report exercise as tending to lower BG. The problem is that not everyone reacts/responds in the same way. For me, something like walking has no real impact. Heavy work, like digging, does reduce my BG, but once I do something that involves adrenalin, such as football, it raises BG. All short-term impacts, though, and they depend on you not adding any glucose to the system while it's going on. The point of the exercise is to deplete glycogen (how glucose is stored) stores, so that the body replaces those from the "excess circulating glucose". However, I didn't do any exercise at all when I was reducing my BG, and for me it wasn't a factor.
I think it's advisable to avoid a T2 diagnosis if at all possible. There are no real benefits, to my mind. Once diagnosed, you can never be undiagnosed - so here I am, five years in remission, last diabetic/out of normal range HbA1c result January 2020 - and I'm still diabetic and unless they change the rules always will be. I guess you've just had an HbA1c? That should give you at least three months, and more likely six, before you have another. And you will only be diagnosed after an HbA1c at 48 or above (and probably want a confirmatory second test, if the result is close to 48 - because of testing inaccuracies.) You have time.
So you don't need to be in normal range today or this week: but you can start to make progress today or this week.
